LM2574HV: 5V at output

Elisha Tarroza71

Part Number: LM2574HV

Hello!

Can the device withstand a +5V at the output for a short period of time without supply to VIN?

Thank you!

Hi,

Is the VIN pin floating?

The concern is that the VOUT will back feed to VIN if the VIN is pulled down to 0.

Thanks

Hi Arief,

Yes, it's floating.
Will it be fine if that's the case?
